Coolio was arrested Tuesday on an outstanding misdemeanor warrant for driving with a suspended license, Los Angeles police said.
The 44-year-old rapper was released roughly five hours after officers pulled over his gray Hummer around 1:45 a.m. in Hollywood. He posted $10,000 bail.
Officers stopped him because the vehicle's registration was expired, but a check revealed his license was suspended and he had an outstanding warrant, Officer Ana Aguirre said.
Coolio, whose real name is Artis Leon Ivey Jr., gained fame for his 1995 single "Gansta's Paradise."
